Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation application of
International Application No. PCT/JP2015/060005, filed Mar. 30,
2015, which claims priority to Japanese Patent Application No.
2014-074261 filed Mar. 31, 2014. The contents of these applications
are incorporated herein by reference in their entirety.
TECHNICAL FIELD
[0002] The present disclosure relates to a wireless power transfer
system and a vehicle power supply device that supplies electric
power to a vehicle capable of receiving power supply.
BACKGROUND ART
[0003] In recent years, vehicles driven by electric power have been
used.
[0004] This leads to a need for supplying electric power to a
vehicle.
[0005] For example, electric power is supplied to a parked vehicle
by a power supply apparatus.
[0006] The power supply apparatus is capable of supplying electric
power to a vehicle in a wireless manner.
[0007] For example, such an idea has been studied that a vehicle
has a wireless type power supply secondary coil on a bottom part
thereof, and a power supply primary coil is provided below the
vehicle to supply electric power to the vehicle.
[0008] FIGS. 16A and 16B are conceptual diagrams of a wireless
power transfer system.
[0009] The concept illustrated in FIGS. 16A and 16B has been
disclosed in U.S. Pat. No. 8,035,255.
[0010] When the wireless type is employed, it is desired that power
is supplied with a small energy loss from the power supply primary
coil to the power supply secondary coil.

SUMMARY
Technical Problem
[0015] In a wireless power transfer system, electric power is
supplied in a wireless manner from a power supply primary coil to a
power supply secondary coil via a magnetic field formed in a space
between the power supply primary coil and the power supply
secondary coil.
[0016] This feature imposes a reasonable restriction on relative
position displacement between the power supply primary coil and the
power supply secondary coil (such a state that the power supply
primary coil and the power supply secondary coil are not arranged
most closely, i.e., such a state that the center of the power
supply primary coil and the center of the power supply secondary
coil are not aligned when the shapes of the power supply primary
coil and the power supply secondary coil are the same). An attempt
to supply electric power while exceeding the restriction on
relative position displacement leads to failure, that is, a large
energy loss.
[0017] The present disclosure describes a wireless power transfer
system and a vehicle power supply device capable of supplying
electric power efficiently while suppressing position
displacement.

[0106] In FIG. 3, it is illustrated that electric power is supplied
from the power receiving apparatus 120 to the object 171 via a
charging cable 173.
[0107] For example, the fitting member 142 is a rod-shaped member
having a tip pointed in a tapered shape.
[0108] For example, in the fit member 152, a cavity having a
diameter slightly larger than a diameter of a root part of the
rod-shaped member is formed.
[0109] The fitting member 142 enters the cavity of the fit member
152 from the tip part, and the root part is fit with the
cavity.
[0110] The posture/position adjustment mechanism 160 is a mechanism
capable of adjusting a relative posture or position between the
primary coil support member 140 and the secondary coil support
member 150 to change the posture between a releasing posture and a
fitting posture.
[0111] The releasing posture is such a posture that the fitting
member 142 releases the fit member 152.
[0112] The fitting posture is such a posture that the fitting
member 142 is fit with the fit member 152.
[0113] When the posture is the fitting posture, the wireless power
transfer is efficiently performed from the power supply apparatus
110 to the power receiving apparatus 120.
[0114] The posture/position adjustment mechanism 160 may be a
mechanism supported by a foundation and capable of adjusting a
posture or position of the primary coil support member 140 to
change the posture between the releasing posture and the fitting
posture. The releasing posture is such a posture that the fitting
member 142 releases the fit member 152, and the fitting posture is
such a posture that the fitting member 142 is fit with the fit
member 152.
[0115] For example, the posture/position adjustment mechanism 160
is supported by the foundation and capable of adjusting the posture
or position of the primary coil support member 140 to change the
posture between the releasing posture and the fitting posture.
[0116] The posture/position adjustment mechanism 160 adjusts the
relative posture or position between the primary coil support
member and the secondary coil support member such that the
releasing posture is changed to the fitting posture, and the
wireless power transfer is performed from the power supply primary
coil to the power supply secondary coil in the fitting posture.
[0117] The posture/position adjustment mechanism 160 may adjust the
relative posture or position between the primary coil support
member and the secondary coil support member such that reaction
force that acts on the fitting member when the releasing posture is
changed to the fitting posture falls below a predetermined value,
and the wireless power transfer may be performed from the power
supply primary coil to the power supply secondary coil in the
fitting posture.

[0147] When the moving body 174 supports the power supply secondary
coil 121 at the predetermined position in the predetermined posture
and is located between the power supply primary coil 111 and the

and is located between the power supply primary coil 111 and the
power supply secondary coil 121, the posture/position adjustment
mechanism may adjust the relative posture or position between the
primary coil support member 140 and the moving body 174 such that
reaction force that acts on the fitting member when the releasing
posture is changed to the fitting posture falls below a
predetermined value, and the wireless power transfer may be

30 that supports the power supply secondary coil 32. The relative
posture or position between the moving carriage 40 and the
secondary coil support member is adjusted so as to become the
second fitting posture in which the second fitting member provided
at the moving carriage 40 is fit with the second fit member
provided at the secondary coil support member that supports the
power supply secondary coil 32 provided at the vehicle support
structure 30. The wireless power transfer is performed from the
power supply primary coil 21 to the power supply secondary coil 32
in this posture, and electric power supplied by the wireless power
transfer is supplied to the vehicle 5. Therefore, the relative
posture or position between the power supply primary coil 21 and
the power supply secondary coil 32 is adjusted, and electric power
can be efficiently supplied to the vehicle 5 supported by the
moving carriage 40 that moves along the moving path H.
[0403] The present disclosure is not limited to the above-mentioned
embodiments, and can be variously changed in a range not deviating
from the gist of the disclosure.
[0404] Although an exemplary case where the vehicle power supply
device includes the relay apparatus has been described, the present
disclosure is not limited to this exemplary case. The vehicle power
supply device may not include the relay apparatus.
[0405] A plate made of a material that does not affect the magnetic
field may cover the void.
[0406] Although an exemplary case where the present disclosure is
applied to the parking device has been described, the present
disclosure is not limited to this exemplary case. For example, such
a case may be employed that the transfer apparatus or the storage
space is not included.
[0407] Although an exemplary case where a moving mechanism of the
parking device is configured to be an elevator parking device has
been described, the present disclosure is not limited to this
exemplary case. For example, a circulation mechanism may be
employed, such as a box circulation parking device, a horizontal
circulation parking device, a merry-go-round parking device, an
elevator sliding parking device, a plane reciprocating parking
device, a transporting storage parking device, and a two-stage or
multiple-stage parking device.
INDUSTRIAL APPLICABILITY
[0408] According to some aspects of the present disclosure,
position displacement is suppressed and electric power can be
efficiently supplied.
